Glass cullet is recycled glass that has been crushed into small pieces. It is often used as a raw material in the production of new glass containers, fiberglass insulation, and other glass products. The use of cullet in glassmaking has several environmental benefits, including reducing the amount of waste sent to landfills and conserving natural resources.
Because glass is infinitely recyclable, it can be recycled over and over again without losing any of its quality or purity. When glass is recycled, it is sorted by color, cleaned, and crushed into cullet. The cullet is then melted and molded into new glass products. Using cullet in glass production can significantly reduce the amount of energy required to melt raw materials, which in turn reduces greenhouse gas emissions. Additionally, using cullet in glass production can help to conserve natural resources such as sand, soda ash, and limestone, which are used to make new glass products.
It is processed by controlled thermal or chemical treatments to increase its strength compared with normal glass, about four times stronger than annealed, glass. When broken, tempered glass fractures into small, relatively harmless pieces, it is widen used for window, door, railing, furniture, vehicle.
